Answer:
The male cone
Explanation:
The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity.
The equation for the reaction between KOH and HCl is as follows
KOH + HCl ---> KCl + H2O
the stoichiometry of KOH to HCl = 1:1
the number of KOH moles reacted = 0.5 mol /1000 cm³ * 30 cm³
= 0.015 mol
the number of HCl moles reacted = number of KOH moles reacted
therefore HCl moles reacted = 0.015 mol
the molarity of HCl is 0.2 mol/dm³
0.2 mol of HCl in - 1000 cm³
Therefore volume required for 0.015 mol = 1000 cm³ / 0.2 mol * 0.015 mol
= 75 cm³
Therefore 75 cm³ of HCl is required
The major idea behind why having a thick, heavy chimney over a thin, metal chimney for heating a home for a longer period is because it retains a lot of heat and this means energy saving, hence it fuel efficient and cost effective
A metal is a good conductor of heat, this property will make it easily give out head that is needed to the surrounding especially at night, therefore a thick chimney especially made from clay material will be a better choice over a thin metal

Answer:
Prokaryotic are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleotide.
Explanation:
All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.
